Okay...I'm a sailor on a budget, so please, any answers short of hauling the boat out would be great. Back in August, I ran Honu up onto an oyster bar (my friends call me Captain Runaground). After finally getting the boat off of the bar, I noticed that no water was coming out of the exhaust. After some time, I finally found that the seacock is clogged (I discovered this by disconnecting the hose, and opening the valve... no water). Please bear in mind that this is the seacock for my raw water cooling system, and that the nearest marina capable of hauling my boat out of the water is an eleven hour sail from the dock. I've been under the boat with a screwdriver (and dive gear) and the block seems to be inside the boat. Any ideas?
